Question about Pentair 3/4hp 115/230v Booster Pump - La01n

2 Answers

Hi, My booster pump for my pool is very loud. It is a Pentair model number LA01n. It has gotten louder over a period of about 2-3 months. It has a small leak in the front seal and I had the seal replaced. It still leaks and the motor is only louder. At this point is it worth fixing? I'm mostly concerned about the noise, but I'm also concerned about the leak. thanks.

Changing the seal is ok but if the shaft has become corroded then you will not get a true seal. the noise is most probably the bearings and replacing them doesn't always help.
best solution is to replace the whole pump which will give you years of use instead of months

YOUR BEST BET IS TO COMPARE MOTOR REPLACEMENT TO AN ENTIRE PUMP REPLACEMENT
MORE THAT LIKELY ITS PROBABLY NOT A GREAT INVESTMENT TO JUST DO A MOTOR ON A BOOSTER PUMP
YOUR MOTOR IS NOISE IS COMING FROM BEARINGS INSIDE THAT ARE GETTING WORSE AND WORSE
NOW A DAYS I STRONGLY DON'T RECOMMEND EVEN TRYING TO REPLACE JUST BEARINGS THEY NEVER LAST LONG AND ITS ALMOST AS COSTLY

Why does my Pentair Booster LA01N sound as if it is spraying water internally ?


I think it's got air in it - that's what cavitation sounds like. Is the pickup gathering some air? Do you have an air bleeder near it someplace, or a valve you can use to bleed air out of it?
